I've been messing around with creating my own "shield" shader, the basic idea is something like this - which can be seen in planetside 2: now rendering the basic shield on a mesh is not a problem, the problematic parts come when I want to create the "borders" you can see in the video where the shield touches the building itself. The same borders also appear when say a vehicle or player passes through the shield. Other effects im looking into creating is a "wave/circle" type of effect when a bullet hits the shield for example.

Anyway, I'm not looking for cut n paste shader code, but more for general pointers in the right direction to achieve these effects.

OMG too long video can you capture that specific effect?

I think I can tell you about idea or implementations.

Post-process reading framebuffer. Mixing red and the input color, combining transparency from 3D animated Perlin noise (third dimension is time), and modulated by a decal texture for the outpost owner's insignia in the middle. Values read from the back buffer have some simple "sinus noise" kind-of-wiggly offset to texture coordinates applied to give a slight, cheap distortion.

When something passes through, just add a value to the noise value with a little decal there (slowly enlarging for a nicer effect). Or, do something like a "2D water simulation" if you feel like burning 1000x the GPU cycles for 0.001% better looks.
